Algae Oil Information
See the following sections:
Fundamentally, algal oil is similar to oil from traditional oil crops / oilseeds.
Reference: Chemistry & Structure of Fixed Oils
Fixed oils from seeds, nuts & vegetables are typically composed of triglyceride molecules (also known as triacylglycerol or triacylglyceride). A triglyceride is a glyceride in which the glycerol is esterified with three fatty acids - a triglyceride is typically composed of a 3-carbon alcohol (glycerol) plus three 18-carbon (or 16-carbon) fatty acids. The 18-carbon fatty acids are Linoleic acid, Stearic acid & Oleic acid.
The fatty acids may be saturated (with all single bonds), mono-unsaturated (with one double bond) or polyunsaturated (with 2 or more double bonds). Plant fatty acids are usually unsaturated and liquid at room temperature, with one or more double bonds between the carbon atoms (mono-unsaturated and polyunsaturated). A notable exception is the palm fatty acid palmitin which is saturated and contains 16 rather than 18 carbon atoms. Since the plant fatty acids are unsaturated, the plant oils it is liquid at room temperature.

Cis & Trans Fatty Acids
Fatty acid isomers containing double bonds may have the cis or trans configuration. In cis fatty acids, all the hygrogen atoms adjacent to the double bonds are on the same side of the longitudinal carbon axis. In trans fatty acids, the hygrogen atoms adjacent to the double bonds occur on alternate sides of the main axis.
The trans configuration is chemically more stable. It is typically produced during partial hydrogenation of polyunsaturated vegetable oils.
Trans fatty acids tend to raise the level of low density lipoproteins (LDLs = bad) and lower the level of high density lipoproteins (HDLs = good). These changes in blood lipids (cholesterol levels) may increase the risk of heart disease (atherosclerosis) in some people. Dieticians generally recommend the use of mono-unsaturated, unhydrogenated oils and the avoidance of trans fatty acids found in french fries, cookies and crackers.
Unsaturated fatty acids found in plant oils and seeds are typically omega-6 fatty acids, in which the first double bond is located on the sixth carbon atom, counting backwards from right to left. Omega-3 fatty acids in which the first double bond in on carbon #3 - are prevalent in fish oils and flax seeds.
